-LRB- CNN -RRB- -- The United Nations said Thursday it would pull about 600 staff members out of Afghanistan in the wake of a militant attack that killed five staff members and wounded nine .

`` At the moment we 're working with the entire U.N. family to identify what is critical staff and what is the support staff that can be moved , '' said Kai Eide , head of the U.N. Assistance Mission in Afghanistan .

The United Nations will also look into `` what kind of activities can take place from elsewhere and what has to take place here , '' Eide said from the capital , Kabul , adding a limited number of staff will be moved within the country .

`` Although details of the new measures can not be made public , it is expected that they will involve short-term relocations for some staff while additional security is being put in place , '' a U.N. statement said .

The United Nations had said it was reviewing its security procedures after the October 28 attack in the capital , Kabul , for which the Taliban claimed responsibility .

`` The United Nations is fully committed to helping all of Afghanistan 's people , as it has been for more than half a century , '' the statement said . `` Every effort will be made to minimize disruption to our activities while these additional security steps are being taken . ''
